  • This study was to identify and quantify the flavor compounds in cream cheese and cholesterol-removed cream cheese made from whole milk powder stored at $7^{\circ}C$ for 4 wk. Flavor compounds of cream cheese were identified using gas chromatography mass spectroscopy and quantified by gas chromatography. The tentatively identified flavor compounds were mainly eight from fatty acids in cream cheese made from whole milk powder (CCWMP) and nine from fatty acids in cholesterol-removed cream cheese made from whole milk powder (CRCCWMP). In quantitative analysis of the flavor compounds, most of the volatile compounds were slightly increased during storage. N-Decanoic acid was produced only in CCWMP. On the basis of the results, it was concluded that the quality and quantity of flavor compounds in CCWMP and CRCCWMP have almost no adverse effects in comparison with that of whole milk-made cream cheese.

  • This study was aimed to compare the texture and sensory properties of Cream cheese and cholesterol-removed Cream cheese made from the whole milk powder (CRWMP) during storage at $7^{\circ}C$ for 4 wk. The cholesterol reduction by crosslinked ${\beta}$-CD was about 92% in CRWMP. In texture studies, hardness, gumminess, and chewiness had increased during the storage period of 4 wk in both cheeses, irrespective of treatment. In the sensory properties, cooked milk flavor was found to have decreased, whereas sourness had increased with increasing storage period of 4 wk in whole milk powder Cream cheese. On the basis of our results, we conclude that the cholesterol removal in CRWMP does not cause any adverse effect on the texture and sensory properties of Cream cheese made with whole milk powder.

  • Soy milk prepared from soy protein concentrate was added with each of four types of milk products. Acid production and growth of five species of lactic acid bacteria(LAB) in soy milk and sensory property of soy yogurt were investigated. Acid production by LAB increased in proportion to concentration of milk products added to soy milk. Among the four milk products tested, whey powder or skim milk powder stimulated acid production by LAB more than whole milk powder or modified milk powder. Stimulating effect by whey powder on acid production by LAB was greater than other milk products at low concentration. Acid production by LAB in soy milk added with glucose or milk products significantly increased during fermentation. Sensory property of soy yogurt added with whole milk powder or skim milk powder was better than that of reference (soy yogurt added with glucose) while sensory property of soy yogurt added with whey powder or modified milk powder was Inferior to that of reference.

  • Milk powders were made by several drying methods and raw materials, and rheological properties of milk powders were investigated by an Instron Universial Testing Machine. The results obtained are summarised as follows. Bulk density of the drum dried whole milk powder was $0.382\;g/cm^3$ and was higher than that of other milk powders. The Hausner ratio, angle of repose and compressibility of the spray dried skim milk powder were 1.127, $32.5^{\circ}$ and 0.029 respectively. This result indicated that skim milk powder showed free flowing characterristics. The compressibility of the drum dried whole milk powder was decreased by the decrease of moisture content. Compressibility of the milk granule was 0.056 and was lower than that of milk powder. The spray dried milk powder of a grobular shape had higher solidity than the freeze or drum dried milk powder. The drum dried milk powder particles consist of irregular shape.

  • Onions contain antioxidant flavonoids and bioactive sulfur compounds. These substances are more abundant in the peel than in onion flesh. For this reason, whole onions including peels were added to soy milk to produce soy milk with whole onions (SWO), whereas peeled onions were added to soy milk to produce soy milk with peeled onions (SPO). The functional and antioxidant properties of these two kinds of soy milk were then analyzed and compared. Compared to control soy milk (CS) without onion powder, treated samples (to which freeze dried onion powder was added at 1.4, 1.6, 1.8, and 2.0%, respectively) showed significantly increased amounts of quercetin, isoflavone, and total phenol (p=0.05). The magnitude of the increase rose as the amount of added onion powder increased and when onion powder contained onion peels. With regards to antioxidant activity (DPPH and ABTS), SWO showed a greater value than SPO. The sensory evaluation scores of SWO and SPO were lower than CS for roughness and swallowing, as adding onion powder increased solid contents and viscosities. However, higher overall acceptability were obtained 1.8SPO and 1.8SWO.

  • This study was performed to determine the feasibility of developing a healthy yogurt using tofu whey concentrates separated by nanofiltration (NF). The curd yogurt was prepared from whole milk with added skim milk powder, in which the NF powder was substituted at 0, 6.25, 12.5, or 25% for the skim milk powder. The quality characteristics were evaluated for pH, titratable acidity, viscosity, color, and viable cell counts. There were no significant differences in pH or titratable acidity between the control (yogurt with added skim milk powder only) and the yogurts with added NF powder, after 24 hr of fermentation at $37^{\circ}C$. The apparent viscosities of the yogurts with added NF powder were higher ($3,197{\sim}3,574\;cps$) than that of the control yogurt (3,196 cps). Lightness decreased, while yellowness increased, as the amount of NF powder increased. Sensory evaluations showed that the NF powder could be substituted for the skim milk powder at 6.25% without lowering the yogurt quality.

  • This study was carried out in order to investigate the effect of additives on Jeungpyun (fermented and steamed rice cake) Preparation. Soy bean flour, whole milk Powder, skim milk Powder, egg yolk, egg white, and mugwort were added in the Preparation of Jeungpyun. There were not significantly difference in loaf volume between control and experimental groups addfd egg yolk, egg white and mugwort. In sensory evaluation, the hardness of Jeungpyun containing of soy bean flour, milk Powder, and egg were lower than control The Jeungpyun containing mugwort was more bitter and harder than the control. The rheological properties measured by texturometer were significantly different among the Jeungpyun added with different kinds of additives. The hardness was significantly lower in Jeungpyun containing whole milk Powder and soy bean flour and springiness was higher in mugwort Jeungpyun compared with the control. In 4$^{\circ}C$ storage, retrogradation of Jeungpyun assessed from hardness measured by texturometer was delayed by addition of soy bean flour and whole milk powder.

  • An in vitro liquid culture media for the cultivation of entomopathogenic nematode Steinernema carpocapsae was developed. Supplementation of whole milk powder with basal liquid culture media showed a remarkable increase in productivity compared to that without whole milk powder and the maximum nematode concentration reached about $1.5{\times}10^5/mL$ within 20 days. Five to twenty gram per liter of liver extract addition revealed highest pathogenicity against 3rd instar of Galleria mellonella which was above about 90% mortality after 48 hr.

  • One of the most critical issues in the dairy industry, alongside the low birth rate and the aging population, is the decrease in demand for milk. In this study, the consumption trends of 12 major dairy products distributed in Korea were predicted using a logistic model, the Gompertz model, and the Bass diffusion model, which are representative S-shaped growth models. The 12 dairy products are fermented milk (liquid type, cream type), butter, milk powder (modified, whole, skim), liquid milk (market, flavored), condensed milk, cheese (natural, processed), and cream. As a result of the analysis, the growth potential of butter, condensed milk, natural cheese, processed cheese, and cream consumption among the 12 dairy products is relatively high, whereas the growth of the remaining dairy product consumption is expected to stagnate or decrease. However, butter and cream are by-products of the skim milk powder manufacturing process. Therefore, even if the consumption of butter and cream grows, it is difficult to increase the demand of domestic milk unless the production of skim milk powder produced from domestic milk is also increased. Therefore, in order to support the domestic dairy industry, policy support should be focused on increasing domestic milk usage for the production of condensed milk, natural cheese, and processed cheese.
